Toy Dataset With a Continuous Outcome For Illustration

Description

These data are provided for the purposes of illustrating the use of the software when the outcome of interest is continuous. Though these data were generated to mimic conditions of a clinical trial, they should not be interpreted as representing true clinical trial data.

Usage

data(tLagIntCont)

Format

The dataset provides three data.frames: b.data.cont containing the basic observed data on 245 enrolled subjects at the time of an interim analysis, with columns with headers

• "subjID" - unique subject identifiers,

• "u" - minimum of time lag or censoring time,

• "delta" - time lag/censoring indicator, and

• "Y" - the outcome if it is available, = 0 if not.

• "a" - treatment indicator;

x.data.cont contains the baseline covariates for the 245 subjects.

• "subjID" - unique subject identifiers,

• "X1" - a continuous covariate;

and t.data.cont contains time-dependent covariate information comprising "subjID" and 6 measurements of a single continuous covariate measured at times (t1 = 0, t2 = 4, t3 = 12, t4 = 24, t5 = 52)
